Üdv mindenkinek!! Adott egy suzuki vagoner és egy kenvud autósrádió,a rádió tökéletesen működik ha áll a motor, de ha be indítom az autót a rádió hangja neki áll szaggatni,nem recseg hanem ki ki hagy.Ha az autó be melegszik ez a folyamat szite teljesen meg szűnik.A rádiót meg tápláltam közvetlenül az aksiról-- semmit nem változik a dolog. A dolog érdekessége, hogy szinte csak gáz adáskor jelentkezik ez a jelenség, de jellemzően inkább csak menetközbeni--gyorsítási alkalomkor, ha áll az autó és úgy pörgetem fel a motort akkor szinte nem is mutatkozi a jelenség. Ha valakinek van valami ötlete, próbáltam a rá olvasást a szemmel verést ,.... de semmi nem változott. Üdv Sallaan1
Kenwood KD67-F lemezjátszóhoz milyen tű ?
Sziasztok! Csereérett lett a lemezjátszómban a tű, szerintetek mi a különbség ezek közt? http://www.ebay.com/itm/Needle-Turntable-Kenwood-N-67-N67-Sansui-SN-P212-/261045663066 és http://www.ebay.com/itm/KENWOOD-SANYO-MARANTZ-SANSUI-TURNTABLE-NEEDLE-STYLUS-819-D7-/270408521961
Trio-Kenwood: KR-3010 [Radio] S.N.962845 / Does not work, the final floor and prefinal floor defect with many burned component/

I greet you! I would need the scheme of this "vintage" amplifier that needs to be "restored". The problem is that in the prefinal and final floor I have many "fried" resistors well, their value cannot be identified.I replaced the defective transistors: 2SC1509, 2SA777,2SB690 and 2SD 796 (each 2 pcs.) and the electrolytic capacitors adjacent to them. I could not go further because of the carbonized resistors that I do not know their value (I can only guess that they are values small, in the order of ohms). The schematic diagram I downloaded, from the address received by the kindness of a colleague is not complete - it is a single page (missing Q29-Q30-Q31-Q3 and resistors R115-R116-R117-R118 which are completely carbonized, at other resistors I could see their value).Thanks in advance!
Finally, I found the missing part

If stuck in the repair and you ask questions, please do it as follows: - Details: Give the exact model number of your device and the chassis ID (if there is). - If possible, please attach pictures of the appliance. - Anamnesis: Write down the exact symptom. If hard to describe the symptom, it is difficult to verbally defined clearly, attach pictures or sound of the phenomenon! - Tell what was you have done so far: search contact error, which parts has examined or changed yet, etc... The incorrectly named topic suspended and will be deleted after 48 hours! Suspended state while others are not able to comment until you correct the address. Subsequent repair of the defective title (within 48 hours) by clicking on the "Edit" tab can be carried out.
